What is Rework?

Rework parts are rejected parts that can still be sold to the customers. Rework refers to the output yield or units that did not pass the quality check the first time and are sent to be corrected.

Rework refers to the process of correcting or repairing a product that did not meet the required specifications or quality standards during the initial production process. It involves redoing certain steps or operations in the manufacturing process to bring the product up to the required quality level.

Rework can occur due to various reasons, such as human error, equipment malfunction, or design flaws. It is a common practice in many manufacturing industries to ensure that the final product meets the customer's expectations.

However, excessive rework can lead to delays in production, increased costs, and reduced productivity. Therefore, it is essential to identify the root cause of rework and implement corrective actions to prevent it from occurring in the future.

In OEE, there is no separation between rework parts and reject (waste) since they were not produced correctly the first time around, and hence do not affect OEE.
